Potential food crops uptake and human exposure
Plant uptake is an important process to transport PFAS to food chain.
Is it safe to eat the food I grow in my garden?Currently, there is no recommendation against eating local produce. DEQ and DHHS arecontinuing to review the scientific literature related to plant uptake of GenX and otherchemicals in the same family (per‐ and polyfluoroalkyl substances, or “PFAS”). Studieshave shown that some other chemicals in the PFAS family can be found in variableamounts in plants and vegetables, but the amount depends on the particular chemicaland the plant type. Direct testing of garden produce for GenX has not been conducted by
NC DEQ, and to our knowledge results of such testing are not available from other sourcesat this time. A study conducted by the Minnesota Department of Health found that the a
mount of exposure to five other PFAS compounds from plants and vegetable sources wasmuch lower than the amount of exposure through drinking water, and concluded that thebenefits of growing and eating homegrown produce outweighed the potential risk fromlow levels of PFAS (https://deq.nc.gov/news/key‐issues/genx‐investigation)
